In a neutral stable carbon atom with a mass of 11. Determine the number of protons,
neutrons, and electrons.
Number of Protons:
Number of Neutrons:
Number of Electrons:
Answer:
A neutral stable carbon atom with a mass of 11 has the atomic number 6, which means it has 6 protons in its nucleus. The number of neutrons in a carbon atom can vary, but the most common isotope of carbon has 6 neutrons.
In a neutral atom, the number of electrons is equal to the number of protons. Therefore, a neutral carbon atom with 6 protons would also have 6 electrons.
So to summarize, a neutral stable carbon atom with a mass of 11 has:
6 protons
6 neutrons (for the most common isotope)
6 electrons
Explanation:
A neutral stable carbon atom is an atom that has no net electric charge and is not undergoing any chemical reactions. This type of atom is said to be "stable" because it has a balanced number of protons and electrons, which gives it a neutral electric charge.
The number of protons in an atom is known as its atomic number, which is unique to each element and determines the element's identity. The atomic number of carbon is 6, which means that every carbon atom has 6 protons in its nucleus.
The number of neutrons in an atom can vary, but the most common isotope of carbon has 6 neutrons. Atoms of the same element known as isotopes differ in the number of neutrons they contain in their nuclei. The number of neutrons in an atom affects its mass, but not its atomic number.
The quantity of electrons in a neutral atom is equal to the number of protons. Electrons occupy the electron shells surrounding the nucleus, and the number of electrons determines the element's chemical properties and behavior. In a neutral carbon atom, there are 6 electrons to balance the 6 protons in the nucleus.
In conclusion, a neutral stable carbon atom with a mass of 11 has 6 protons, 6 neutrons (for the most common isotope), and 6 electrons. This gives the atom a neutral electric charge and is representative of the atomic structure of the element carbon.

What contribution did John Dalton make to atomic theory? a. He discovered that every atom was positively charged. b. He discovered that atoms had nuclei. c. He discovered that every element consisted of one type of atom. d. He discovered that atoms could be divided into smaller parts.
John Dalton's main contribution to atomic theory was the idea that every element consisted of one type of atom. Option C is correct.
In the early 19th century, John Dalton proposed that all matter is made up of small, indivisible particles called atoms. He also suggested that atoms of the same element are identical in their physical and chemical properties, and that atoms of different elements combine in simple, whole-number ratios to form compounds.
While Dalton's atomic theory was not completely correct (for example, atoms can be divided into smaller parts, as in the case of subatomic particles), it was an important step in the development of modern atomic theory.

what is the relationship between temperature and molecular motion
Temperature and molecular motion is a)directly proportional to each other. On increasing temperature,molecular motion also increases. So, correct option is a.
Molecular motion is characterized as the development of constituent particles or particles in a specific heading. The Molecular motion are impacted by intensity and temperature. This is on the grounds that temperature is the estimation of the typical dynamic energy of the atoms and addresses the movement of particles.
Essentially, heat moves energy among constituent particles that increment the motor energy of atoms. The numerical connection between active energy and temperature can be displayed underneath;
E = kT
where, E=Energy, k=boltzmann steady, T=temperature
The various kinds of molecular motion are
Translational movement: In such sort of movement, particles can move starting with one spot then onto the next in the equivalent or different bearing yet consistently stays on a similar hub.
Rotational movement: In this sort of movement, the particle can turn in and around the pivot.
Vibrational movement: In this kind of movement, particles can vibrate at their mean position. These movements are extremely normal in strong state.
Electronic movement: In this kind of movement, electrons can move from one spot to another and orbital to orbital. Electronic movements cause an adjustment of the shade of substances.
Hence,correct option is a.

Slip is an acid-resistant resin used to make aquatints. true or false
Slip is an acid-resistant resin used to make aquatints is a false statement.
Slip is an acid-resistant resin used to make aquatints. Tempera, gouache, and watercolor are all water-based paint media. Because oil paints dry quickly, it is difficult for artists to make changes to their paintings.
The process of making aquatints involves, fine particles of acid-resistant material, such as powdered resin, are attached to a printing plate by heating. The plate is then immersed in an acid bath, just like etching. The acid eats into the metal around the particles to produce a granular pattern of tiny indented rings.
